no energy off, gang. no energy off. the name of the game for any power production, if you're burning coal, is have less mass afterwards than you started. you got energy. if you got more mass afterwards than you started, you had to take in energy. but energy be given off if you got less mass afterwards than you begin. so in this side of the curve, on this side of iron, what do i have to do? break apart or do what? what's the other word? instead of break apart, what do i wanna do? fuse them. i wanna fuse them, honey. i wanna fuse them. i wanna take these isotopes here and i wanna fuse them together. let's suppose i take some high-- that's what the sun and the stars do. take some hydrogen, huh. hydrogen, look at all the mass it's got, yeah? now, take those hydrogen-- [makes sounds] --squash them together. easy or hard to do? hard. very hard to do, electrical repulsion. but if you could squash-- and sun and the stars do that, squash them together-- [makes sounds] --now, it's helium. helium got less mass per nucleon than the
